Rollup merge of #78873 - tmiasko:inline-opts, r=oli-obk
Add flags customizing behaviour of MIR inlining * `-Zinline-mir-threshold` to change the default threshold. * `-Zinline-mir-hint-threshold` to change the threshold used by functions with inline hint. Having those as configurable flags makes it possible to experiment with with different inlining thresholds and substantially increase test coverage of MIR inlining when used with increased thresholds (for example, necessary to test #78844).
